DETAILED DESCRIPTION OF THE INVENTIONAs required, detailed embodiments of the present invention are disclosed herein; it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limits, but merely as a basis for teaching one skilled in the art to employ the present invention. The specific examples below will enable the invention to be better understood. However, they are given merely by way of guidance and do not imply any limitation.
In one embodiment, the present invention uses Polyglutamic acid (PGA) as the hydrophilic polymer. PGA has been used as a long term skin hydrating, plumping material. The material helps bind water to the skin, plumping the stratum corneum, adding to skin firming and reducing lines and wrinkles.
These polymers have usually been in the one to two thousand Dalton ranges with the maximum molecular weight of 10,000 Daltons. Recently, breakthroughs in biotechnology have produced polymers in the 2 to 3 million Dalton range. These high molecular weight PGAs retain much more water on the skin than the lower molecular weight ones. They actually hold more moisture than the Industry standard, hyaluronic acids, that have molecular weights in the 2 million Dalton range. In addition, a special grade of PGA was employed in this invention. A PGA with a molecular weight of about 2 million Daltons, that is additionally cross-linked. This cross-linking helps render the polymer to be more long lasting on the skin surface. It makes it less sensitive to degradation by skin enzymes and other agents. The high molecular weight cross-linked PGA provides a longer lasting firming and plumping effect than that of other PGA's and hyaluronic acid.
In yet another embodiment, the present invention may use Mandelic Acid which is a large molecular weight alpha hydroxy acid. Mandelic acid contains an aromatic ring that makes it slow to penetrate the upper layers of the stratum corneum. This helps to have a much more prolonged effect on the skin than other alpha hydroxy acids like glycolic or lactic acids. The skin resurfacing action of mandelic acid has numerous benefits: firstly, it has been shown to clip off dead surface skin cells, and secondly, makes the action of PGA better by giving it a smooth undisturbed surface to bind moisture to. Thusly, mandelic acid contributes to the skin firming and smoothing benefits of the skin care formulations of the present invention.
In still another embodiment, the desquamatory agent may be N-acetyl glucosamine (NAG). NAG has shown to give excellent results in skin smoothness, firming and reducing lines and wrinkles. It acts as a natural skin desquamatory, gently clipping off skin surface cells that are remaining on the surface too long. There also appears to be a retinoid-like effect of increasing collagen synthesis and improving dermal thickening. NAG assist in making the skin denser and less lined and wrinkled. The addition of NAG to mandelic acid and cross-linked PGA, appears to yield an optimum amount of skin firming that is recognizable on test subjects in two to four weeks.
